ROOF AND TILE THEREFOR.

Specification of Letters Patent.

Patented Apr. 11, 1916.

Application filed November 16, 1914. Serial N 0. 872,305.

To all whom it may concern:

Be it known that I, JAMns S. DUFFY, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Roofs and Tiles Therefor, of which the following is a specification.

The object of my invention is to provide a novel, simple and efficient roof or side Wall and tile therefor, the roof or side wall comprising a suitable base and a plurality of courses of tiles thereon constructed and arranged, first, so that the tiles may be interchangeable and reversible for convenience of assembling, secondly, so that the courses of tiles may be expanded and contracted both longitudinally and transversely of the courses to properly fit roof bases of different sizes, thirdly, so that individual tiles may be readily removed from a roof or side wall for repairing, fourthly, so that the assembled tiles may be securely held in place with few nails and without driving nails through the faces of the main bodies of the tiles, fifthly, so that, in manufacturing the tiles, they may be cut from a rolled or other suitably formed bar having the same crosssectional shape throughout its length, and. so that the tiles may be out from the bar with little or no waste, and, siXthly, so that various novel and advantageous results may be attained.

roof base covered with a plurality of courses of my improved tiles, certain tiles in the upper right hand corner of the figure being removed for clearness of illustration. Fig. 4 is a section, on line L4' of Fig. 3. Fig. 5 is a section, on line 5-5 of Fig. 3. Fig. 6 is a view showing one method of forming the tiles.

Referring to the drawings, my improved tile comprises a body portion 2, a long rib :1 3 and a'short rib 6. The body portion '2 is provided with a long edge portion 7, a short edge portion 8, opposite to the long edge portion 7, and two other edge portions 9 which diverge from the ends of the short edge portion 8 to the ends of the long edge portion 7. The ribs 3 and 6 are formed straight or substantially so, and they are arranged parallel to each other or substantially so. The long rib 3 projects from one face of the body portion 2 along the long edge portion 7 thereof, and the short rib 6 projects from the opposite face of the body portion along the short edge portion 8 thereof, as shown.

A number of the tiles are employed in forming the improved roof illustrated in Figs. 3, 4 and 5, in which the tiles are arranged on and secured toa suitable base 10 which may be of any suitable construction;

diverging edge portions 9 0f the intervening tiles 18 which have their short edge portions directed upwardly.

The tiles 12 of each course are in alinement with each other parallel to their ribs,

having their long ribs directed upwardly and their short ribs directed downwardly; and the tiles 13 of each course are also in alinement with each other parallel to their ribs, having their long ribs directed downwardly and their short ribs directed upwardly. The ribs of the tiles 12 of a course 11 cross the space or joint between the ribs of the tiles 13 of the same course. The long ribs 3 of the tiles 12 of a course 11 are in alinement and are directed upwardly at the top of the course; and the long ribs of the tiles 13 of the samecourse are in alinement and are directed downwardly at the bottom of the course, as shown.

Each course 11 intervening between the uppermost course and the lowermost course, has its lower portion'overlapping the upper portion of the next course below it and has its upper portion overlapped by the lower I portion of the next course above it. The

downwardly-extending ribs 3 and 6 along the lower edge of each course is hooked over the upwardly-extending ribs 3 and 6 along the upper edge of the next course below; and the bottom faces of the long ribs 3 and the tiles 1?) of each course 11 rest upon the top faces of the tiles 12 of the next course below, as clearly shown in Figs. 4 and 5.

The upper portion of the uppermost course of tiles 11 may be finished by any suitable covering member; and the lower portion of the lowermost course of tiles 1.1 may rest upon the base 10. The tiles of the different courses are secured to suitable strips 16 on the base 10 by suitable nails 14 which are driven through the ribs 8 and 6 of two tiles 12 of two adjacent courses and into the strips 16, as clearly shown in Fig. 5, so that a single nail will serve to secure the upper end of one tile and the lower end of another tile to the base 10. The strips 16 being properly spaced 0n the base 10 before applying the tiles, serve as spacing devices for the courses of tile.

It will be readily uriderstood that the arrangement and association of the tiles as hereinbefore described and as shown in the drawings will cause all water reaching the roof to flow therefrom by gravity down over the upper faces of the tiles and prevent the water from passing through the courses of tiles.

It will be observed that the end tiles of each course 11 are formed with their outer edges extending at right angles to the ribs 3 and 6 to present a straight edge at the end of the roof. By varying the spaces between the tiles 12 and the spaces between the tiles 18 of a course and by adding tiles to Or removing them from the course of tiles may be longitudinally expanded or contracted to properly fit a roof base of a given size; and by sliding the lower portions of the courses over the upper portions of the adjacent courses upon which they rest and by adding or removing courses an entire set of courses may be expanded or contracted transversely of the courses to fit a roof base of a given size.

In Fig. 6 I show the manner of cutting the tiles with very little waste, from a long straight bar 15 of the same shape in cross section throughout its length as the shape of-the tiles in cross section. The bar 15 may be formed by a rolling operation or by forcing su table material through suitable dies. The tiles may also be cast or otherwise formed if desired.

I claim:

1. In combination, a supporting base, and a plurality of courses of tiles thereon, each tile having a body portion provided with a long edge portion and a short edge portion and other edge portions diverging from the ends of the short edge portion to the ends of the long edge portion, each tile having a long rib projecting from one face of the body portion along the long edge portion thereof, each tile having a short rib substantially parallel to the long rib and projecting from the other face of the body portion along the short edge portion thereof, each alternate tile of a course having its long and short edge portions overlapping the short and long edge portions, respectively, of the intermediate tiles of the same course, and the short rib of each tile of one course crossing a joint between the long edge portions of two adjacent tiles of the same course.

2. In combination, a supporting base, and a plurality of courses of tiles thereon, each tile having a body portion provided with a long edge portion and a short edge portion and other edge portions diverging from the endsof the short edge portion to the ends of the long edge portion, each tile having a long rib projecting from one face of the body portion along the long edge portion thereof, each tile having a short rib substantiallv parallel to the long rib and projecting from the other face of the body portion along the short edge portion there of, each alternate tile of a course having its long and short edge portions overlapping the short and long edge portions. respectively, of the intermediate tiles of the same course, the ribs of the tiles along one edge of one course lapping the ribs of the tile along one edge of the next adjacent course. the long ribs of two adjacent tiles of the same course being in alinement with each Other and the joint between them being crossed on each side thereof by two short ribs of tiles of two adjacent courses.
